vgsp-disp: unconditional pushbuffer receipt log + NvBool valid fix

Log every NV2080_CTRL_CMD_INTERNAL_DISPLAY_CHANNEL_PUSHBUFFER (0x20800a58)
receipt with the decoded 56-byte params struct, and always log rejected
channel registrations and SET_NOTIFIER_DMA - boot-only volume, settles
whether the kernel RM ever programs the display push buffers through
that control (r1621 follow-up).

valid is an NvBool (1 byte); the previous u32 load could read the
padding bytes and turn a PIO-channel valid=0 into a false positive.

Raise the engine log budget to 4096.
